Finally a general purpose pancake prime to go with the 16mm, so there will be two pocketable options for the NEX system.

For KAP though the Sigma 19 mm f2.8 has been available for a while in a NEX E-mount version. It is usually about half the expected price of the Sony 20 mm. The Sony will weigh 68 g (2.4 oz) compared to the Sigma 139 g (4.9 oz), so that is a benefit for KAP. The Sigma has a good reputation and I very much doubt if the Sony lens will be any better.
